Abstract

Method for the production of an optical coupler for polymer light-guides by arranging the light-guides in the same direction and bundling them by means of a plastic shrink-fit sleeve. In this method, two to 10<5> polymer light-guides are arranged in the same direction and bundled and a plastic tube is slipped over the mixing zone. Subsequently, a piece of plastic shrink-fit sleeve is pushed over the plastic tube and the shrink-fit sleeve is heated to a temperature at which it contracts. The shrinking temperature of the shrink-fit sleeve is within the thermoelastic temperature range of the plastic tube. The light-guide bundles may be stretched during or after heating.
